This invent-ion relatesto sole edge coating machines and is*herein illustratedas fembodied" in a machine particularly designed for applyingwax-to the edges of the soles of boots andshoes prior to burnishing operations; I

Inorder to improve the eiiect of the burnishing operation upon the edge of-the sole of a shoe, which operation is commonly called edge setting, itjirequently isfound desirable to apply-wax to the edgeoi the sole prior to the *burnishing operation so that a higher polish will be'obtained and-one which will be more permanent; In-someinstances the wax is applied from "a stick which' is rubbed over the edge wax and irregul ar '111 results mainly because of; the; difficulty in transferring the desired to each part of the sole small quantityof wax edge in a -properlymolten condition. It is that the waxes most suitable for this purpose, carnauba' wax being an example of suchva wax, are those whichare relatively hard and brittle at ordinary temperatures'but which can be readily applied when they are liq uefied by the application o'fheat, It is d flic-ult to transfer to a sole edge-wax from a stick end, brush or sponge without cooling off the wax to such an extent that it readily chips off the sole edge when a burnishing or' othertool first comes into contact with it and such difliculty'increases with increasing hardness of the wax.

Accordingly, one important object of the invention is to providejan' improved-machine by means of which the 'edgesof the soles of boots and shoesmay bc'"co'ated-evenly" and thoroughly and the operation performed even more r'apidly than by hand and without requiring the-use of skilled labor.

in the illust'ratedlmachine wax is applied to the fwork by means of a'driven-rollwhich preferably is constructed of absorbent ma- 1 terial 'su'ch as'ielt and the 'wax isdeliyered SJ to this felt rOltfroma supplying roll which ofthe sole-, and in other cases the waxis liquefied andapplied with receives reservoir. Since shoes "are only intermittently presented tothe -applyirig'= roll, it" is impossible exactly to coordinate the supply of w axw'iththe amount whichis used'up on the shoes. It has beenf0und,"however,that an even application of wax to-the p-ieces of work may lee-assured by means of a novel ari-"a'ngement 6f the; above-mentioned parts.

ture ofthe invention, the supplying roll is independently driven "to "rotate toward the upper part-ofthe app1yingi-o11 and the waX is depositedupon the upper surface of the supplying other roll. trated, he applying roll rotates in the opposite direction from that of the supplying roll so that its upper part alsoapproachs the latter r011; This results in storing up a small quantity ful reserve of wax supply and rendering- 1t unnecessary to set'the'flow of waxirom the l reservoir to the supplying wheel with'great exactitude. V

Such aielt roll, while applying a uniform coating when "new; is easily deformed by the pressure of thework and may become-so misshapen that it -110 longer applies the wax evenly; In accordance withfanother feature of the invention and as illustrated, the supplying roll=hasan end flange whichoverlaps the'end of the applyingfroll 'so' that in addition to the contact of the periphery of the roll there'isan engagement of the flange with the end of the felt roll and a sharp corner is' maint'ain'ed upon the [felt rollas well illustrated, also -V as an ven periphery-Pets the felt roll is mount den aprojectionof its driveshaft and is h ld against axial removal by the flange the supplying roll.

As illusplie'dir to. ithefieltirollz through thistiflange.

This arrangement preferably also includes means for minimizing the transfer of heat to the shaft driving the applying roll so that the lubrication thereof will not be affected.

In accordance with still other features of the invention, the applying roll of the illustrated machine is supported in a bracket mounted upon an upright pivot and arranged so that the pressure between the applying roll and the supplying roll may be adjusted to give a degree of control of the quantity of wax which the felt roll will give up. Carried upon the illustrated bracket for adjustment with the applying roll and in adjustable relation thereto, are a plurality of gages arranged for use alternatively in accordance with the style of work to be treated. One of these gages, for example, is intended for engagement with the bottoms of the soles of mens shoes where the edges are substantially normal to the bottoms. WVhen it is desired to use the machine for womens shoes, the other gage, which is a crease gage in the form of a rotatable disk, is preferably utilized, this gage projecting slightly beyond the periphery of the felt roll to engage the crease between the upper edge of the sole and the shoe upper. This gage is supported upon the carrier for the applying roll both for adjustment of position with respect to the periphery of that roll and also for bodily displacement with respect thereto.

These and other featuresof the invention are more fully described herein, reference being had to which Fig. 1 is an end elevation of the machine; Fig. 2 is aplan view thereof; Fig. 3 is a detail view of the applying roll showing the crease guiding disk in use; h Fig. 4 is an end view on an enlarged scale of said crease disk and the support therefor; and

the accompanying drawings, in

Fig. 5 is a front elevation of the shoe bot- 1 tom engaging gage showing its relation to the work and to the applying roll.

The application of wax is effected by means of a cylindrical applying roll 10, preferably constructed of felt, and coacting with this is asupplying roll 12 having an end flange 14 which overlaps the edge of the applying roll for purposes to be more fully described. As will appear from Fig. 1, these rolls are rotated in opposite directions such that the upper portions of the rolls approach each other and to this endthe applying roll is carriedfby a shaft 16 (F i'g. 2) having a drive pulley 18, while the supplying roll 12 is mounted upon a shaft 20 having a drive pulley 22. Power is supplied to these pulleys from any suitable source to efiect their rotation at such speeds that the peripheral speeds of the two rolls are substantially equal. The shaft 20 is journaled in bearings 24 mounted on a base 26 while the shaft 16 is journaled in bearings 28 and 30 which are formed upon a carrier 32 mounted to swing about an upright pivot 34 which is clamped in a depending arm 36 forming a part of the base 2 A spring-pressed plunger 38 bears against the carrier 32 to swing it in one direction so as to move the applying roll 10 away from the roll 12 and an adjusting screw 40 is provided for moving the carrier against the tension of this plunger 38 thereby to adjust the pressure between the peripheries of the two rolls and to determine the amount of wax delivered to the felt roll 10. When the screw 40 is turned far enough to bring the felt roll 10 out beyond the flange 14 of the supplying roll 12, the felt roll 10 may be easily removed from its shaft 16.

The supplying roll 12 is a metallic roll, preferably hollow as indicated in Fig. 1, and heated by a flame from a gas jet supplied by the pipe 42. The heating of the felt roll 10, because of its combustible nature, is not so easy, however, and for this reason the roll 10 is supported as shown in Fig. 3. It will be seen that a carrying member 44 constituting an extension of the shaft 16 is provided to support the felt roll 10 and this carrying member 44has a flange 46 at the back of the roll and a central projection 48 of reduced diameter upon Whichthe felt roll is mounted by endwise positioning movement. In orderto make sure that the felt roll will be rotated with the carrying member 44, the flange 46 is also provided with a pin 50 which enters the felt roll when the latter is mounted on the shaft. It is possible, with this arrangement, to supply heat to the felt roll by a gas flame 52, to which gas is supplied through a pipe 54, directed against the rear face of the flange 46, thus permitting the heat to be transferred to the'felt roll without setting it afire. In order that the heat supplied to the carrying member 44 may not 7e transferred back to the shaft 16 and there by interfere with the lubrication of thebearings 28 and 30, said extension is secured to the shaft 16 by an insulated mounting comprising a projectingend portion 56 on the extension which is received within a recess formed in an enlarged portion 58 of the shaft 16 and is held therein by screws 60 spaced around the enlarged portion 58 and furnishing means for centering the extension upon the shaft 16. At the same time the screws furnish a minimum path for the transfer of heat back to the shaft 16, an d the air between the projection 56 and the recessed portion 5 8 helps to insulate the tool. h

It may be desired to supplywaxes of different colors to different batchesof work and to this end a plurality of wax pots 62 and 64'are adapted to be alternate y positioned a-bove'the supplying roll 12. The interchange of these pots is facilitated by mounting them upon an upright pivot'66 in wax is delivered dropqby outlet nozzle rier 32 for adjustment the screw 40 is turned. 'These are. not;;1n--

WVhen this gage is not to beused it may be swung to an inoperative position or removed from the machine.

The guide disk 7 6 is preferably mounted as shown 1n Flg. 2 so as to lie at a slight angle to the outer faceof the felt wheel-110 with that portion of it which projects radially be yondthe periphery of the felt wheelnearest' thereto, therebeing less likelihood of undesired transfer ofwax from the felt to the guide disk by such mounting. I

A change of. the color of wax desiredneces screw comes into upright side of the sitates a change of the feltroll 10. Such change is facilitated by the above. described mounting of the shaft-1.6.: since it is only necessary. tov turnthe screw 40 outwardly far; enough for the felt roll 10 to. be brought clear of theflange 14-so-that it may bewithdrawn from the-end of its-carrying member 44' uponwhichit'is held as. above described] merely by. being threaded .over a central pin smaller pin 5.0 which is. eccentric rotatethe-rolllO. When iuopera-tion, the

outer edge of the felt roll 10 is overlapped by, the flange 14 on the metallic roll 12 and thereis no necessity for provision of further means for holding the feltroll longitudi-' nally of the member 44. p c c In effecting a change of felt roll from one V the roll 12;

felt roll which is maintained saturated with molten wax. The outline of a shoe with a 1 screw so that the plunger '88 moves the shaft 16 so as to withdraw the felt roll 10 from overlapping relation with the flange 14,

\1 he will then remove the felt roll and change T0 it for another,

clean off anywax there may be on the metallic roll 12 and move the de sired wax reservoir 62 or 64.- into position, and will finally by turning the screw 40 cause the renewed felt roll to make contact with In the actual operation of applying wax to sole edges an operator takes each shoe and manoeuvres it with 1ts sole edge against the portion of its forepart sole edge in contact with the felt roll is shown at 78in Fig. 1. By

traversing the sole past the felt roll a film' r of wax is applied all around the sole edge by a constantly changed and constantly recharged applying surface, giving as a result a thin film of wax well impregnated into the sole edge surface.

When the metallic and felt rolls 12 and 10 f) are heated and rotated as above described and "3 low the line where the rolls are closest in wax is fed to the former, it is rapidly transferred to the felt roll 10 and there is a tendency for waves of molten wax tobe mainh tained on the rolls immediately above and be contact. The size of these waves depends upon the excess of wax fed to the metallic roll 12 over that removed from. the felt roll 10 by the work. The formation, however, of

if) these waves produces a useful reserve wax supply since a considerable quantity of wax may be retained in such wave formation and used up by continued application of fresh work to the felt roll. Under such conditions manipulation of the nozzle screw position and held there by engagement of the "4 5* it is not necessary to set the flow of wax from the reservoir on to the metallic roll with. great exactitude, and the delivery of wax to the metallic roll may be, if desired, effected manually from time to time as necessary by l 72.

Variation of the pressure with which the felt roll 10 is pressed (by reason of adjustment of its shaft) against the metallic roll 12 causes corresponding variation in the 5?? quantity of wax which the felt will readily give up when work is held against it. If a free wax delivery is desired the pressure between the two rolls is reduced, as above indicated, by adjustment of the screw 40.

b?!- If mens work or work of a similar style in which the sole edges are Hat and substantially at right angles to the sole sin'faces, is to be presented to the machine, then the bottom gage 74 will be raised to its operative lation' of the shoe, keeping V fittedwith low heels, it may be desired to wax the heel edge surface as well as the sole edge. In such a case the gage spindle 82 may be moved'laterally by means of pressure applied to the treadle rod 100 so as to expose a greater width of the surface of the felt roll.

If, on the other'hand, womens work is to be treated, the gage shown in Fig. 5 will be dropped to a vertlcal inoperative position, as

indicated in Figs. 1 and 2, and the work will be'guided in engagement with the crease dish 76, as indicated in Fig. 3.
